Rubens Tube

Let me explain what these are. If you havent noticed yet, Ive changed the featured video found lower on this page to one entitled Rubens Tube still alive. A rubens Tube is a straight tube with holes perforated across the top. Both ends are sealed with one end hooked into a speaker and the other to a valve connected to flammable gas. When the gas is turned on, it gets pushed into the tube and out the holes across the top. When the speaker is turned on it sends sound waves into the tube which pushes the gas out of the holes in perfect waves. SO when a note is hit, the sound wave for that note is seen with the lit flammable gas being pushed thru the openings across the top of the tube. Visual sound waves represented with fire, how cool is that?
